Abstract: A device for skin-contact biological measurement includes one or more electrodes to enable signal transmission through a skin contact and a control mechanism coupled to the one or more electrodes to adjust an electrode-to-skin impedance (ESI). The control mechanism is configured to implement the ESI adjustment using a thermal actuator.

Abstract: Embodiments are disclosed for full body pose estimation using features extracted from multiple wearable devices. In an embodiment, a method comprises: obtaining point of view (POV) video data and inertial sensor data from multiple wearable devices worn at the same time by a user; obtaining depth data capturing the user's full body; extracting two-dimensional (2D) keypoints from the POV video data; reconstructing a full body 2D skeletal model from the 2D keypoints; generating a three-dimensional (3D) mesh model of the user's full body based on the depth data; merging nodes of the 3D mesh model with the inertial sensor data; aligning respective orientations of the 2D skeletal model and the 3D mesh model in a common reference frame; and predicting, using a machine learning model, classification types based on the aligned 2D skeletal model and 3D mesh model.

Abstract: A wearable electronic device includes a housing, and an electrode carrier attached to the housing and having a nonplanar surface. The wearable electronic device includes a set of electrodes, including electrodes positioned at different locations on the nonplanar surface. The wearable electronic device includes a sensor circuit and a switching circuit. The switching circuit is operable to electrically connect a number of different subsets of one or more electrodes in the set of electrodes to the sensor circuit.
